Diodes Incorporated AH3360-FA-EVM

Overview

AH3360-FA-EVM from Diodes Incorporated is an evaluation module for the AH3360 high-sensitivity, micropower unipolar Hall-effect switch IC in X1-DFN1216-4 package. It enables functional validation of magnetic actuation (south-pole activation), ultra-low 4.3µA average supply current at 1.85V, 1.6–3.6V operating voltage range, and hysteresis-controlled switching (BOP = 30 G typ., BRP = 20 G typ.) in portable consumer and industrial proximity sensing applications.

For engineers reviewing the AH3360 datasheet, AH3360 pinout, AH3360 application, or AH3360 equivalent, this EVM supports rapid prototyping of cover-detect, lid-switch, docking, and contactless position-sensing circuits with verified power sequencing, noise-immune output behavior, and thermal stability across –40°C to +85°C.

Technical Context

The AH3360-FA-EVM implements a chopper-stabilized Hall sensor architecture with internal sleep/awake logic, delivering ±10 G magnetic hysteresis (BHY) and <0.1 µA output leakage. Its board-level design replicates the IC's internal pull-up/pull-down capability and integrates a 100 nF CIN capacitor per datasheet Note 4 for supply stabilization and RF noise immunity.

The module operates exclusively in unipolar mode-output activates only when a south pole exceeds BOP (16–42 G) at the marking side-and maintains latched state until flux drops below BRP (11–35 G). No external biasing or timing components are required beyond the onboard decoupling network.

FAQ

What is the purpose of the AH3360-FA-EVM?

The AH3360-FA-EVM is a dedicated evaluation module for the AH3360 unipolar Hall-effect switch IC in X1-DFN1216-4 package. It provides a ready-to-use platform with properly routed power, ground, and output traces, pre-mounted 100 nF decoupling capacitor, and test points for validating magnetic actuation timing, supply current, and output behavior under real-world conditions without custom PCB design.

Does the EVM support all AH3360 package variants?

No. The AH3360-FA-EVM is specifically configured for the X1-DFN1216-4 package (FA suffix), as indicated by its part number and physical layout. It does not accommodate the X2-DFN2015-6 (FT4) or SOT553 (Z) variants due to differing pin counts, pad geometries, and thermal pad configurations-each requires a dedicated evaluation board.

How is magnetic field polarity tested on this EVM?

The EVM exposes the top surface of the AH3360 die location aligned with the part marking side. Per datasheet specification, the output activates only when a south magnetic pole is presented perpendicular to that surface. Polarity verification is performed using a calibrated magnet with known pole orientation; no external circuitry or polarity inversion is needed-the IC's native unipolar response is directly observable at the OUTPUT test point.

Can the EVM operate from a 1.8 V coin cell?

Yes. The AH3360-FA-EVM fully supports the IC's 1.6 V to 3.6 V operating range. At 1.8 V, it draws ≤4.3 µA average current (typical), enabling multi-year runtime on CR2032 cells. The onboard 100 nF capacitor ensures stable startup and noise immunity even at minimum supply voltage, consistent with DS35744 Rev. 3–2 requirements.
